MARYLAND, A CORPORATION OF MARY- GAS nonnina Application led November 3,1927. Serial No. 280,868.

This invention pertains to gas holders and more particularly to thattype commonly known in theart as waterless gas,l holders. Such type ofholder is set forth and claimed in the United .States patent toJagschitz, No. 1,275,696, dated August 13th;

The present invention has todo with a specific form of sealing meansemployed between the movable closure and the adjacent face of the wallof the body of the reservoir.

The invention, in a sense, is an improvement upon the constructionsshown in my copending applications Serial Nos.\143,765 and 143,766,filed October 23, 1926. Said cases, in a generic sense, involve the useof capillary brous material designed to be carried by the movableclosure and to be held in sealing relation to the adjacent face of thewall of the reservoir, means being provided for supplying a lubricating,sealing medium to such brous material.'

The present invention embodies the same fundamental idea in conjunctionwith means lsurel moves upwardly or downwardly, as the case may be. ,f

Several embodlments ofthe invention are shown in the accompanylngdrawings where- Figures 1, 2 and 3 are sectional elevations i of so muchof the closure and the wall of the holder as is necessary to anillustration of the invention, the diierence between the `structureslying primarily in the-means for supplying the sealing, lubricatingmedium to the fibrous sealing material, and

Figure 4 is a top plan view of a portion of the means employed forforcing the rubbing bars outwardly against the holder wall, said barslikewise reventing curling or turning of the ends o the sealing materialas above In the drawings, Yhaving reference more particularly toFigures-1 and 4, 1 denotes the wall of the body ofthe gas holder and 2the movable closure or piston-like member, the latter being somewhatsmaller in diameter than the internal diameter of the shell of theholder. Y

Secured to the lower portion of the closure isa rigidv outwardlyextending structural element 3'which forms the support for a bracket orshelf 4 which extends entirely' Overlying the fibrous elements 5 is amember 8 which acts to hold the fibrous elements in position. Thismember of course extends entirely around'the closure.

`As will be seen, the upper and lower layers of the sealing element donot extend outwardly into contact with the inner face of the wall of theholder and associated with said relatively narrow upper and lowerelements is means to prevent curling of the layers as the closure movesupwardly and downwardly within the'shell. In connection with the upperportion I provide a se ries of plates 9 formed of metal having a certaindegree of flexibility, which plates, as will .be seen-u on reference toFigure 4, have their ends o -set and stand in overlapping relation. Thelower edges o said plates extend downwardly past the outer edge ofV theuppermost layer of felt or librous material. Said plates are ur edoutwardlyinto .contact with the wall o the holder by a lever 10, thelower end of which is pivotally connected as at 11 to -a bracket 12secured to the plate. The lever is fulcrumed as at 13 to an arm 14rigidly secured to the closure 2, the lever at its upper end beingprovided with a weight 15 through the adjustmentl of which requisitepressure mayfbe exerted upon the plate 9 to force the same outwardly.

A second and duplicate series of plates of like form and arrangement,the plates 9, one of which plates of the second series is designated 9afor the sakeof clearness, is positioned below the bracket, the upperedges of the plates extending upwardly beyond the outer edge of thelowermost layer of felt, said plates being urged outwardly against thewall of the holder through any suitable mechanism. In the presentinstance, I have shown a lever as 1G fulcrumed at its inner end to adownwardly extending bracket 17, the lever at its opposite end beingupturned and ful crumed at 18 upon a bracket 19 secured to the plate.

A weight 20 adjustably mounted upon the lever 16 tends to rock the leverand toforce the plate 9 outwardly into contact with the wall of theholder.

From the foregoing it will be seen that the plates 9 and 9 prevent theouter edges of the fibrous material from curling upwardly or downwardlyas the closure rises or falls.

In Figure 2 the same general arrangement as to the means employed forpreventing the curling of the edges of the felt is illustrated but inthis instance the oil is fed from a separate tank 21 through a pipe 22into a chamber 23 which is formed in rear of the feltor fibrous closure.Parts which are duplicated in Figures 1 and 2 are similarly lettered.

In Figure '3 the same arrangement of plates for preventing the curlingof the felt sections is shown but the felt sections in this instance aremuch wider and their inner portions are down-turned and extend into areservoir 24;

, filled with the proper lubricant.

It is of course conceivable that insofar as the generic invention isconcerned a single layer of fibrous material, provided it be thickenough, might be employed in conjunction with the plates, hence theinvention is not to be limited to a sealing medium formed of a pluralityof elements.

The use of a plurality of layers is, however, advantageous over a singlelayer particularly where bolt heads or rough places may protrude fromthe inner face of the wall of the shell; the plurality of layers willmove over such projections with greater facility and without leaving anyopening through which the gas may escape.

What is claimed is:

1. In a waterless gas holder the combination of a shell; a movablepiston-like closure located therein; an absorptive sealing mediumcarried by said closure and contacting the inner face of the shell;means for holding a body of liquid in contact with the inner portion ofthe sealing medium and by which latter the liquid is carried outwardlyinto contact with the inner face of the shell; and means cooperativewith the upper and lower faces of said medium and at its outer edge toprevent displacementor curling of the same as the closure moves up ordown.

2. A waterless gas holder as set orth in claim 1 wherein the meansCooperative with the sealing medium comprises a series of flexibleplate-like elements urged outwardly into contact with the wall of theholder shell.

3. In a waterless gas holder the combination of a shell; a movablepiston-like closure therefor; an absorptive sealing medium Carried byand surrounding the closure; means forholding a body of liquid inContact with the inner portion thereof; a series of plates extendingaround the inner face of the holder, the ends of the plates overlapping,with the edges of said plates contacting the adjacent face of thesealing medium; and means act ing to force said plates into face-wiseContact with the inner face of the wall of the holder.

4. In a waterless gas holder the combination of a shell; a movablepiston-like closure therefor; a fibrous sealing medium carried by andsurrounding the closure, said medium being produced from a plurality ofsuperimposed felt layers; means for holding a body of liquid in Contactwith the inner portion thereof; a series of plates extending around theholder above and below said felt layers, the ends of the platesoverlapping and the edges of said plates contacting the adjacent face ofthe sealing medium where it bears against the inner face of the wall ofthe holder; and means acting to force said plates into face-wise contactwith the inner face of the wall of the holder.

5. In a waterless gas holder the combination of a. shell; a movablepiston-like closure located therein; an absorptive sealing medium 100formed from a plurality of superimposed layers carried by said closure,the outer face of said sealing medium contacting the inner face of theshell; means for holding a body of liquid in contact with the innerportion 105 of the sealing medium; and means cooperative with the. upperand lower portions of said medium at its outer edge to preventdisplacement or curling of the same as the closure moves up or down.

6. In a waterless gas holder the combination of a shell; a movablepistonlike closure located therein; an absorptive sealing mediumextending around the closure, the outer face of said medium contactingthe inner face 115 of the shell; means for holding a body of `liquid incontact with said sealing medium;

and means cooperative with said medium at its outer edge to preventdisplacement or curling thereof during movement of the closure. 1'20 Intestimony whereof I have signed my name to this specification.
